Mr. Zeldin (R-Shirley) will now prepare to redeem himself on November 4 after his first run for political office six years ago against Congressman Tim Bishop (D-Southampton), in which he earned 41 percent of the vote compared to the incumbent’s 58 percent.

Despite the previous results, he said he believes his odds are much better this time around in a midterm election, which national pundits widely agree can often bring fewer Democrats to the polls.

“In 2008, there were certainly factors that were out of our control that are not the same dynamics now,” Mr. Zeldin said Wednesday morning. “Barack Obama was much more popular than he is today. People were suffering from [former President George] Bush fatigue and the war in Iraq. And the economy at the end of September really started to get a lot worse.”

Personally, he pointed to experience he’s since gained at the legislative level — he was elected to the New York State Senate in 2010 — which has brought him more name recognition, a pool of campaign volunteers and better campaign financing.
Despite all that, Mr. Demos outspent Mr. Zeldin throughout the primary campaign at a rate of more than three-to-one, spending over $1.9 million compared to Mr. Zeldin’s $580,000.

Mr. Demos — who ran in two previous primaries, in 2010 and 2012 — said he was unsure what the future would hold for him.
“I want to continue to be involved in public service and fight for conservative principles,” he said. When asked if he might run again for public office, he said he hadn’t decided yet.

A spokesman for Mr. Bishop, Keith Davies, released the following statement after Tuesday’s race.

“As the campaign goes forward, [Lee Zeldin] is going to have a very hard time defending his far-right, tea party-aligned positions, such as supporting a government shutdown and privatizing Social Security, which are totally out of sync with mainstream Long Island voters.”

Mr. Bishop will be running for his seventh consecutive term after defeating challenger Randy Altschuler in his last two campaigns.
